FLOOR AND CEILING CONSTRUCTION.

EFECIFICATIO'I forming part of Letters Patent No. 678,683, dated July 16, 1901. Application tiled April Z7, 1901. Serial No. 57,679. (No, model.)

To @ZZ whom t may concern.-

Beit known that I, TIMOTHY OSHEA, a citi- Zen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Floor and Ceiling Constructions, of which the following is a specification.

My invention relates to certain improvements in licor and ceiling constructions, the objects being to lighten the structure without lessening the rigidity thereof, to firmly brace the structure against wind-pressure, to provide against the passing of sound from one floor to another in the building, and to certain other details of construction, a description of which will be found in the following specilication and definitely pointed out in the claims.

In the drawings, Figure l is avertical crosssection of a oor and ceiling structure containing my improvements, the line of section being indicated at line l l of Fig. 2. Fig. 2 is a plan of the parts seen in Fig. l with the flooring-boards removed and certain other portions broken away. Fig. 3 is a vertical cross-section inline 3 3 of Fig. 1. Fig. 4L is a detail vertical cross-section in line 4. dof Fig. 1. Fig. 5 is a perspective view of aportion of a ceiling-supporting web and a secondary ceiling, and Fig. 6 is a detail vertical section in line G 6 of Fig. 1.

In the views, A A represent two of the stringers commonly used in iioor and ceiling constructions, the ordinary form being that of I-bealns having horizontal flanges a a' at the top and bottom, respectively. These I- beams are ofcourse supportedin the ordinary manner, which is familiar to those skilled in the art. Upon the I-beams are hung the trans'- versely-extending lioor and ceilingsupporting members B C, which are firmly tied together, preferably by wires b, as seen in Fig. l, and thus tightly clamped upon the iianges a d of the I-beanrs. The lloor-supportingmemberis preferably made up of flanged Webs b b2, riveted together and notched at their ends to lit over the flanges a of the I-beams, leaving tongues b4 resting thereupon, the contiguous ends of said tongues abutting against each other to brace the structure laterally. Upon the web b2 is securely riveted a truss comprising substantially a V-shaped member t, ex-

tending froin the ends of the tongues b and down to the middle ofthe lower edge ofthe web, and two diagonally-extending braces b7 bs, eX- tending down beyond the lower edge of the web to form legs to rest upon the lower flanges a. of the I-beams. This truss enables the webs to carry the weight of the [ioor with perfect safety, although it is a very light construction.

Upon the webs b' Ware secured corrugated metal sheets E, preferably by nailing them thereto, the nails e being driven in between the contiguous faces of the webs b b2, thus connecting the sheets with the webs and greatly adding to their lateral rigidity. The furring and floor strips (lettered CZ and CZ, respectively) are secured upon the top of the corrugated strips, the furringstrips being first nailed to the floor-strips and then secured to the webs in the same manner as the corrugated sheets, the nails d2 in this case being driven through the sheets and in between the webs h b2, as clearly shown in Fig. et. The space between the furring and flooring strips may then be filled in with concrete or other suitable material F and the iiooring D nailed to the ooring-strips d.

The ceiling-supporting webs C are provided with downwardly-extending tongues c, each containing a perforation c and a projecting smallertang c2. This web C supports a metallic ceiling composed of metal sheets G, containing perforations g to receive the tongues c, and when said plates are crowded up against the bottom of the web they are secured thereto by means of pins c3, thrust through the holes c in the tongues. EX- panded metal lathing II or other suitable lathing to support the plaster is then secured below the metal ceiling G by passing the tangs c2 through its meshes and bending the tangs up against the lathing, as seen in Fig. 6. This completes the construction, and the lathing may be plastered in the usual inanner, as seen at I.

The construction above described provides a perfectlyrigid framework capable of sustaining heavy loads, the different parts of course being properly proportioned'to the Weight to be carried, and by separating the licor-supporting webs B from the ceiling-webs C any sound upon the floor will not be trans- IOC mitted as readily to the ceiling as it would be in case the members B and C were one sheet. The structure is also perfectly fireproof, the space between the plaster and metal ceiling G being a non-conductor of heat, and said sheets and the corrugated sheets E prevent water from escaping from the floor above to the floor below.

More or less variation of the different parts is possible, and I desire, therefore, not to limit myself except as specifically set out in the following claims.

I claim as new and desire to secure by Letters Patentl. In a construction ot' the class described, the combination with a series of I-beams, of a series of transversely-extending webs supported upon the Ibean1s and notched at their ends to receive the flanges thereof and a truss-frame comprising the V-shaped member, h6, the ends of which rest upon the I- beams and the legs, 197, ha, resting upon the lower flanges of the I-beams; substantially as described.

2. In a construction of the class described, the combination with a series .of I-bearns, of a series of transversely-extending flanged webs supported thereon and notched at their ends to receive the upper flanges of the I- beams, the truss-frameJJG, 57, 58, resting upon the flanges of the I-beams and adapted to stillen the webs in a vertical plane and metal sheets, E, secured upon the tops of the Webs for stiffening them laterally; substantially as described.

3. In a construction of the class described, the combination with a series of longitudinal stringers, of a series of transverse Webs having downwardly-extending tangs, c2, a metal ceiling supported on said webs and metal ornes lathing secured and supported upon said tangs; substantially as described.

4. In a construction of the class described, the combination with a series of longitudinal stringerspf a series of transversely-extending webs having perforated depending tongues, and upturned tangs, a metal ceiling having perforations to receive said tongues, pins secured in said perforations to support said ceiling and a metal lathing secured upon said upturned tangs; substantially as described.

5. In a construction of the class described, the combination with a series of I-beams, of a series of transversely-extending llanged webs notched at their ends to receive the upper flanges of the I-beams and ceiling-supporting webs resting against the lower lianges of the I-beaxns and wires, b, connecting said Webs to clamp them tightly upon the I-beam; substantially as described.

6. In a construction of the class described, the combination with a series of I-bearns, of Hoor-supporting webs having the tongues, b4, resting upon said I-bearns, a truss-frame comprising a member extending from said tongues down to the middle lower edge of the web and the legs, 117, 08, resting upon the lower flanges of the I-beams and a ceilingsupporting web resting against the lower edges of the I-beams and suitably connected to the floor-supporting webs; substantially as described.

In witness whereof I have hereunto set my hand at Chicago, in the county of Cook and State of Illinois, this 24th day of April, A. D. 1901.
